Datum.
Parts are composed of a number of surfaces, each surface has a certain size and mutual position requirements. The requirements of the relative position between the surfaces of the parts include two aspects: the dimensional accuracy of the distance between the surfaces and the relative position accuracy (such as axes, parallelism, verticality and circular runout, etc.).
The study of the relative position relationship between the part surfaces can not be separated from the datum, and the position of the part surface can not be determined without a clear datum. In its general sense, the datum is the point, line and surface on the part on which the position of other points, lines and surfaces are determined. According to its different functions, the benchmark can be divided into two cat ...
What Is MIG Welding?
MIG welding is the process of joining metal parts by melting the base metal and fusing it with a filler metal. The name is derived from the phrase "Metal Inert Gas," which is commonly used. The process involves using an arc between an electrode and the workpiece, which melts the base metal and fuses it with the filler metal.
Mig welding is an extremely versatile process that can be used to create virtually any shape or configuration of the welded joint. You can also use it for many different metals, including low carbon steel, stainless steel, and aluminum alloys.
Mig Welding Equipment
The MIG welding equipment you'll need includes:
Torch
The torch supplies the heat needed to melt the wire. It has a handle, an on/of ...
